  1. diskpart
  2. list disk
  3. select disk # (# is the number of the hard drive with which you have the disk error)
  4. attributes disk clear readonly

You can terminate the Command Prompt, return to the upgrading/downloading process, and verify if the Steam disk write error Windows 10 solved or not.

  1. Move Steam Game Folder to another Drive

  2. Select the games you need to replace the location.
  3. Shift the games to the target drive.
  1. Check Integrity for Steam Game Files

Just check integrity for Steam games folders at first if you see games keep failing or their models missing unknowingly.

  1. Reboot the system and then start Steam.
  2. Choose the LIBRASY tab and right-click the game that transmits disk errors and press on Properties.
  3. Tap on the Local Files tab, and then you can see the Verify Integrity Of Game File key. Press it.

Steam begins checking game folders, which may need a couple of minutes. Please note that some files may decline to check, which is common for most Steam games. That’s because these folders are local configuration files, and they cannot be displaced as part of this action.

When all folders are verified successfully, you can retry installing updates and see whether the disk error is eliminated.
